### Summary
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/254
For all chains except Solana, the data in `globalTransactions.sourceTx` was somewhat duplicated, since we already had that data in the `vaas` collection.
This pull request changes the `tx-tracker` service so that no redundant data will be written, and also changes the API to look up the data from the `vaas` collection instead.
The responses from the endpoint `/api/v1/global-tx` will no longer contain the field `originTx.from`.
### Summary
This pull request adds the functionality to search for VAAs using Solana tx hashes, e.g.:
`GET /api/v1/vaas?txHash=2qnNNBQQQ152sGkQ1Rnq2Kdr48LvdN4oXwnTWyEmJqYYWFusLWxbwhpGS5KTXH1bKKx9gg9BLZMKd3g1cXiy7QMz`.
Also, the VAA objects returned by the API now have a new field `nativeTxHash`, which contains the tx hash that generated the VAA in the native format of the emitter chain.

### Testing guidelines
Endpoints affected:
* `GET /api/v1/vaas` now supports Solana tx hashes by using the `?txHash=` query parameter. This search is limited to VAAs created by the portal token bridge.
* Some VAAs returned by the API should have a new field `nativeTxHash`. All VAAs related to the portal token bridge should have this field set.
* An internal refactoring affected pretty much all routes under `GET /api/v1/vaas*`, which should be re-tested.
* In the response of `/api/v1/global-tx/`, the field `originTx.signer` has been renamed to `originTx.from`
### Summary
The tx-tracker service was exceeding node RPC rate limits, which caused it to fail.
This pull request changes the APIs upon which the service depends to avoid the same issue in the future.
Also, the backfiller job has been updated accordingly.

### Summary
This pull request adds a new component under the directory `txtracker`.
This component retrieves information about portal token bridge transfers (i.e.: sender address, receiver address, timestamp), and persists the data in MongoDB.
### Chains supported
The blockhains currently supported are:
* Terra (27% of outgoing transfers)
* Solana (25%)
* BSC (25%)
* Eth (14%)
* Polygon (4%)
The remaining chains will be added iteratively as needed.
* Add use of sequence cache in API
* Add sequence cache in fly
* Deploy for API
* Improve use cache in API
* Remove sequence cache in fly for pythnet
